Features

AI Translation
  • Up to 32 X (transmit) lines and 20 Y (receive) lines for use by a touchscreen and/or key array
  • A maximum of 640 nodes can be allocated to the touch sensor
  • Touchscreen size of 9.7 inches (16:10 aspect ratio), assuming a sensor electrode pitch of 6.5 mm. Other sizes are possible with different electrode pitches and appropriate sensor material
  • Multiple touch support with up to 16 concurrent touches tracked in real time
  • Up to 32 nodes can be allocated as mutual capacitance sensor keys in addition to the touchscreen, defined as 1 key array
  • Support for up to 3 mutual capacitance Generic Keys as an alternative to the touchscreen key array
  • Adjacent Key Suppression (AKS) technology is supported for false key touch prevention
  • On-cell/touch-on display support including OLED and LCD (ITPS, IPS)
  • Discrete/out-cell support including glass and PET film - based sensors
  • Synchronization with display refresh timing capability
  • Support for standard (for example, Diamond) and proprietary sensor patterns
  • Works with PET or glass, including curved profiles
  • 10 mm glass (or 5 mm PMMA) with bare finger
  • 6 mm glass (or 3 mm PMMA) with multi - finger 5 mm glove (2.7 mm PMMA equivalent)
  • Support for non - rectangular sensor designs (for example, circular, rounded or with cutouts)
  • Moisture/Water Compensation: No false touch with condensation or water drop up to 22 mm diameter; One - finger tracking with condensation or water drop up to 22 mm diameter
  • Mutual capacitance and self capacitance measurements supported for robust touch detection
  • P2P mutual capacitance measurements supported for extra sensitive multi - touch sensing
  • Noise suppression technology to combat ambient and power - line noise: Up to 240 VPP between 1 Hz and 1 kHz sinusoidal waveform (no touches); IEC 61000 - 4 - 6, 10 Vrms, Class A (normal touch operation) conducted noise immunity
  • Stylus Support: Supports passive stylus with 1.5 mm contact diameter
  • Burst Frequency: Flexible and dynamic Tx burst frequency selection to reduce EMC disturbance; Configurable Tx waveform shaping to reduce emissions
  • Scan Speed: Typical report rate for 10 touches ≥100 Hz; Initial touch latency <20 ms for first touch from idle; Configurable for power and speed optimization
  • Touch panel failure detection: Automatic touch sensor diagnostics during run time to support the implementation of safety critical features; Diagnostics reported using dedicated output pin or by standard Object Protocol messages; Configurable test limits
  • Reports one - touch and two - touch gestures
  • Output for display backlight control, audible speaker/buzzer output, or simple haptic feedback
  • Lens bending algorithms to remove display noise
  • Touch suppression algorithms to remove unintentional large touches
  • Palm Recovery Algorithm for quick restoration to normal state
  • 32 - byte CRC checksummed data area for use as a run - time Product Data Store Area
  • 64 - byte data area for user’s custom data (not CRC checksummed)
  • Encrypted configuration parameters and touch coordinate reports (OBP messages) using customer's own security key
  • Programmable timeout for automatic transition from Active to Idle state
  • Pipelined analog sensing detection and digital processing to optimize system power efficiency
  • I2C client interface for main communication with the device: Standard mode (up to 100 kHz); Fast mode (up to 400 kHz); Fast - mode Plus (up to 1 MHz); High Speed mode (up to 3.4 MHz)
  • Interrupt to indicate when a message is available
  • Additional Hardware Debug Interface to read the raw data for tuning and debugging purposes
  • Digital (Vdd) 3.3V nominal
  • Digital I/O (VddIO) 3.3V nominal
  • Analog (AVdd) 3.3V nominal
  • High voltage internal X line drive (XVdd) 6.6V or 9.9V with internal voltage pump
  • Operating Temperature: - 40°C to + 85°C
